This seems to happen on Windows only, happened to Thomas and Nathan already.
Similar patch Thomas was showing, but i do not see it committted. So comitting
now in order to get more developers and users happy.
Ever since we merged the extra texture types (half etc) and spit kernel the compile time for cycles_kernel has been going out of control.
It's currently sitting at a cool 1295.762 seconds with our standard compiler (2013/x64/release)
I'm not entirely sure why msvc gets upset with it, but the inlining of matrix near the bottom of the tri-cubic 3d interpolator is the source of the issue, this patch excludes it from being inlined.
This patch bring it back down to a manageable 186 seconds. (7x faster!!)
with the attached bzzt.blend that @sergey kindly provided i got the following results with builds with identical hashes
58:51.73 buildbot
58:04.23 Patched
it's really close, the slight speedup could be explained by the switch instead of having multiple if's (switches do generate more optimal code than a chain of if/else/if/else statements) but in all honesty it might just have been pure luck (dev box,very polluted, bad for benchmarks) regardless, this patch doesn't seem to slow down anything with my limited testing.

It's possible that cancellation occured between the creation of the reader
and the creation of the Blender object, in which case reader->object()
returns a NULL pointer.
BKE_libblock_free_us() was called on the object data, which decrements
its user count, after which the same function was called on the object,
which decrements the user count of the object data again. This double
decrement was too much.
Original code from @Severin with changes from @dfelinto & @hypersomniac.
This doesn't cause many functional changes
besides using new transform manipulators.

The state mask wasnt applied before comparison giving false results. It
shouldnt really happen that a ray state contains any flags that need to
be masked away, but if it does happen its better to not get stuck.
This fixes T51143.
gl_ClipDistance is part of GLSL version 1.3 but Mac is stuck on 1.2 for now.
This workaround uses GPU_SHADER_3D_UNIFORM_COLOR for the entire rotation widget, ignoring any clipping plane. The CLIPPING shader only works on GLSL 1.3+ so I removed its 1.2 cruft.
A legacy implementation using gl_ClipVertex might be possible, but is not worth the effort. This problem (and workaround) goes away when all platforms move to 3.3 core profile.
changes:
- exact vertex count
- take bool (filled vs outline) instead of GLenum
This function has some flexibility that is not currently used. I left that in.
Each function takes a bool (filled vs outline) and a color. We already had multiple ways of passing color in; these are still here. Special variant for anti-aliasing.
- took GLenum out of interface
- removed UI_RB_ALPHA flag (only one place really used it)
- use exact vertex count
- removed redundant state changes (BLEND, LINE_SMOOTH)
This introduces a new CMake option - WITH_LEGACY_OPENGL. Without this option
things may not draw perfectly, however, we should soon be able to build with
OpenGL core profile.
The matrix-related api calls are (still) not handled here (glTranslate, ...).
There seems to be no consensus on whether to make this build option the
default. We can talk about this later. For now two things are the
priority:
(1) To get rid of deprecated calls when WITH_LEGACY_OPENGL is ON
(2) To make core profile work for Mesa/Mac when WITH_LEGACY_OPENGL is OFF

Many thanks for Sergey Sharybin for the help.
Previously, a GHash was used to store a flattened mapping of parent
information based on the Alembic hierarchy, and then that hash was used to
set parent pointers on Blender objects. This resulted in errors and
some duplicate objects. The new approach stores parent pointers while
traversing the Alembic hierarchy, which means that there is much more
information about the actual context of the Alembic object itself,
producing a more stable import.
Also replaced the bool param "to_yup" with "AbcAxisSwapMode mode", so that
it's more explicit that axes are swapped.
Also added unittests for create_swapped_rotation_matrix.
